In a widowed family, the surviving parent and children face the loss together. However, most previous research in bereavement has focused on individual experiences. Although the family perspective has been introduced into the field, neither theories nor empirical research has explored mutual interaction. Dyadic coping reflects the family perspective and has been proven to be an influential factor in couples facing life adversities. Nevertheless, it has not been explored in the context of bereavement-specific stressors, including loss-and restoration-related stressors, nor in the parent-child relationship. This research is the first exploration of parent-child dyadic coping in widowed families in the bereavement context and aims to form a comprehensive conceptualization of parent-child dyadic coping following bereavement. Qualitative semistructured interviews were conducted with 20 parents and children from widowed families in mainland China (11 surviving children and nine widowed parents, representing 19 families). Constructivist grounded theory was used to guide the analysis. The main themes identified were dyadic coping-related cognitions, loss-oriented dyadic coping, restoration-oriented dyadic coping, and contextual factors. Three foci (thou, we, and I) were identified for both loss-and restoration-oriented dyadic coping. A conceptualization model of bereavement dyadic coping within widowed families was developed. This study extends the single I-coping perspective in bereavement coping to a we-coping perspective, provides an interactional-and operational-level knowledge on dual-process coping, acknowledges the bilateral interaction in parent-child relationships, and offers implications for bereavement support practice for widowed families.
